To (ZZZ whom it may concern Beit known that l, FRANK W. BERGER, acitizen of the United States, residing at Willow Lakes, in the county ofcan; and State. of South Dakota,have invented certain new'and usefulImprovements in Neck- Yoke Fasteners, of which the following is aspecification.

My invention relates to the general class of carriages and wagons,particularly to neck-yoke securing means, and has for its object theprovision of such means whereby a neck-yoke may be quickly and easilycon-' nected with or detached from the pole or tongue of a wagon orcarriage or other vehicle or implement, such as reapers, binders,mowers, plows, rakes and the like.

An important object is the provision of neck-yoke securing means whichwill operate to hold the necleyolre more and more firmly in proportionto the pulling strain exerted thereon and on the pole or tongue butwhich will permit ready disengagement of the neck-yoke from the pole ortongue upon reverse or rearward movement of the neck-yoke.

Another object is the provision of a device of this character which willbe simple and inexpensive in manufacture, efficient in use, durable inservice, and a general improvement in the art.

With the above and other objects and ad-' vantages in view, theinvention consists in the details of construction to be hereinafter morefully described and claimed, and illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of the device inposition upon a pole or tongue and engaged by a neck-yoke,

Fig. 2 is a similar View showing the device in releasing position,

Fig. 3 is a cross-sectional view, and Fig. 4- is a detailcross-sectional view.

Referring more particularly to the drawings, the letter A designates apole or tongue and B designates a neck-yoke having an attaching ring C.

Secured upon the tongueis a metallic member including a portion 10secured upon the top of the tongue and a portion 11 secured upon theunder side of the tongue, these portions being connected by a curvedbight 12 spaced from the end of the tongue. Intermediate its ends,the-portion 11 is profipecif eation of Letters 1919. serial no. 298,741.1

vided with an extension 13 wardly fromthe tongue.

isposed beneath the tongue is a member 143 formed of somewhat resilientmaterial which includes a portion 15*secured against the-underside ofthe tongue by U bolts 16 and which is reflexly bent to provide a portion17 extending forwardly of and in spaced relation to the tongue beyondthe extension 13. At its forward end the portion 1'2 is curved, as shownat 18, to extend upwardly into engagement with the tongue and has formedthereon a forwardly extending handle 19 spaced beneath the end portionof the tongue. Formed at the juncture of the handle 19 with the upwardlyextending portion 18 is a rearwardly extending lip 20 which terminatesadjacent the front of the extension 13 and which is curved topractically merge into the under side of the tongue. The resilience ofthe member 14 is such that-the lip 20 will be held against the tongue.

In the use of the device, the operator grasps the handle 19 and pressesdownwardly thereon whereupon the portion 17 of the member 14c will besprung downwardly so that the lip 20 will be spaced from the tongue. Theneck-yoke B is then attached to the tongue by slipping the ring C overthe metallic member secured at the end of the extending downtongue untilthe ring passes between the tongue and the lip 20 and engages againstthe extension 13. The operator then releases the handle 19. When aforward pull is subsequently exerted upon the neck-yoke B the ring Cwill engage the lip 20 and be prevented thereby from being disconnectedfrom the tongue. To detach the neck-yoke the handle 19 is moveddownwardly and the ring C slipped off from the tongue.

From the foregoing description and a study of the drawings it will beapparent that I have thus provided extremely simple and readily operablemeans whereby a neckyoke may be attached to or detached from a wagontongue, the construction being such that the greater the forward pullupon the neck-yoke the greater will be the holding power of the meansholding the neck-yoke.

While I have shown and described the preferred embodiment of theinvention, it will be understood that I reserve the right to make suchchanges in the form, construe tion, and arrangement of parts as will notPatented @ct. ii, ieai.

depart from the spirit of the invention or the scope of the subj oinedclaims.

i parallel Iclaim: c

In combination with a draft pole or tongue and neck-yoke, a neck-yokefastener comprising a metallic member secured upon the end of the poleor tongue and having a "downwardly extending projection spaced from theend thereof, a resilient member secured upon thepole or tongue andextending'along the underside thereof in spaced relation thereto andengaging against the end of-said projection, the forward end of saidresilient member being curved upwardly and rearwardly to define of theneck-yoke when a forward pull is e erted and said projection beingengaged by the ring when a rearward pull is exerted upon the neck-yoke.

, In testimony whereof I hereto afiix my signature.
